Lattice Simplifies Optical Ethernet System Management Interfaces

New reference design enabled multi-gigabit IEEE 802.3 MDIO interface controller based on small, low power, MachXO3 and ECP5 families

HILLSBORO, OR August 6, 2014 - Lattice Semiconductor Corporation (NASDAQ: LSCC) the leader in low power, small form factor, customizable solutions, is helping engineers quickly implement optical Ethernet designs up to 100Gb/s with the publication of a new reference design for IEEE 802.3 Management Data Input/Output (MDIO) interface controllers.

Reference design RD1194 uses the world’s smallest, lowest cost per I/O programmable platform, the MachXO3™ family, or the new ECP5™ family. The ECP5 features the industry’s highest functional density with up to 85k LUTs and SERDES in tiny 10mm x 10mm packages. With their small size and low power, MachXO3 and ECP5 devices are perfect for implementing I/O expansion, bridging or connectivity needed to deliver Multi gigabit Ethernet applications such as CFP2/4 modules.

Designers can use the reference design to implement a simple Wishbone user logic interface that enables the user to access the PHY registers. It supports MDIO IEEE 802.3 Clause 45/22 master/slave controllers and features pre-amble pattern selection through the input port.
